Wind erosion is common in?

  • A.Humid region
  • B.Arid region
  • C.Arid & semi arid
  • D.None of these

Answer: C

Wind erosion is common in arid and semi-arid regions.

Wind erodes soil where the soil is dry, loose and finely divided, the surface has little vegetation, and winds are strong. These conditions occur together in regions of low rainfall: the deserts and semi-deserts. In India, western Rajasthan and parts of Gujarat and Haryana are the main areas.

Humid regions have moist soil and good plant cover, which hold soil against wind; erosion there is mainly by water. 'Arid region' alone is not wrong, but it leaves out the semi-arid regions, which also suffer badly, so the fuller option is the answer.
